    32AWG, 7/6 1.75mm i.d. m.c. = 2.2Ω √
    32AWG, 5/4 2mm i.d., loose m.c. = 1.85Ω √
    30AWG, 11/10 1.75mm i.d., t.m.c. =2.35Ω √
    30AWG, 11/10 1/16-1.58mm i.d., m.c. = 2.1Ω √
    30AWG, 11/10 1/16-1.58mm i.d., m.c. = 2.1Ω √ #292 MrOcelot
    30AWG, 11/10, 1.2mm i.d., t.m.c. = 1.8Ω √ #601 Christopherja
    30AWG, 10/9 1/16-1.58mm i.d., m.c. = 2.04Ω

    Everything all laid out.

    You'll see 2 long legs.

    Feed both legs thru the center hole

    I took the shorter lead and pulled it tight to maintain tension and lightly wrapped it around the bit.

I am using 30ga kanthal, and I have wound 1.8, 2.0, 1.8, 1.9 ohm respectively for the coils I have done, which I am thrilled with. I am wicking these with organic cotton, not boiled.

    Thanks, Mac, and everyone else on this thread for the knowledge.

    If you don't have a ohms reader for your coils this may suffice.... I took the data from the wraps and ohms in the first post by nerak for 28GA, 30GA and 32GA, graphed the data and came up with an equation for wraps vs. Ohms with my trusty ol' TI-84. It should do the job if you use a 1/16 bit or anything very similar to that. The reasoning behind that is the majority of the data came from wraps around 1/16 bits.

    All you have to do is input
